Armored Core: Formula Front

Screenshots:

Background:
Armored Core has always been primarily about mech customization, with the action-based mech battles taking second priority, but in Formula Front, the action-based mech battles have been removed entirely. This game is one giant mech garage, with players selecting parts for their mechs and viewing the results through AI-controlled test matches

Gameplay:
Paint the different parts in different colors, upgrade your mechs' abilities by spending points on any of around eight different attributes, and then give your mech (or its pilot) its own personality by moving five slider bars, which determine such traits as its aggressiveness and whether it prefers to battle by initiating attacks or by counterattacking enemies that are on the offensive
